Do SR-22 rifles have larger the average optic/bore height?

I got my SR-22 decked out with some accessories and an Aimpoint Pro. I sighted the Aimpoint in at about 12 yards because I plan to use mainly for plinking but I took some shots at soda cans at 50 yards, the POI was 6" high.

I got home and measure a optic axis 3.1" above the bore center. So this essentially amplifies the POI shift due to the offset of the optical axis versus the bore axis. It appears at least .5" above my AR-15 wearing a Vortex PST 1-4.

Any suggestions from you guys that have used the SR-22. I think I'll just have to make a decision on what yardage to zero on. If I want a dead hold relatively close it will cost me on the long range.

Thanks for the reply. Those numbers look pretty reasonable, I actually checked them in Strelok to what I had establisbed and my numbers look almost exactly the same. I'm going to plink around with it for a bit as is but I may adjust as you have if I do any distance shooting at all.

I found standard AR co-witness height mounts too high for my SR-22.

I ended up with the lower ADM CASV height QR mount for the Romeo5 MRD.
